Scala: Code coverage for projects with tests in separate modules

Question

For a variety of admin reasons, our projects have the following structure:

someproject-core
someproject-api
someproject-test

The idea is all the tests are in a separate module.

Question: What plugin can I use to get accurate test coverage?

Answer 1

Use Scoverage: https://github.com/scoverage/sbt-scoverage It supports multi-module SBT projects and measures statement coverage instead of line or branch coverages.

BTW there is a nice plugin for Sonar to browse coverage reports: https://github.com/RadoBuransky/sonar-scoverage-plugin
